CEN/TC 230/WG 4 - Performance Requirements for Water Monitoring Equipment

This document specifies general requirements, performance requirements and conformity test procedures for automatic sampling devices (samplers) for water and waste water that:
—   sample water and waste water from non-pressurized (i.e. open to atmosphere) channels or vessels;
—   sample over extended periods to collect discrete or composite samples based on time, event or flow proportional sampling.
It does not include sampling systems built into online and in-line analysers.
The general requirements include functional facilities that samplers need to meet users’ applications and information that needs to be included in associated documents.
The test procedures specify uniform methods to be used when determining key performance characteristics of samplers at one or more set sample volume. It is for the sampler manufacturer and/or user to decide on the required set sample volume(s). All of the test procedures are to be carried out under laboratory conditions. It is recognized that for some samplers, certain test procedures are not applicable.
Statistical procedures are specified for evaluation of the test data. Some example calculations are provided.
Specific sample integrity requirements are specified for samplers to be used for the collection of samples of final effluent or influent for the purpose of monitoring the performance of urban waste water treatment works. Samplers to be used for other industrial applications do not need to be assessed against these specific sample integrity requirements.
This document does not cover the installation and on-going use of samplers.

This European Standard specifies general requirements and performance test procedures for portable and fixed position measuring devices (MDs) that are used in an in-line or online operating position to measure physical and chemical determinands in water. It excludes at-line devices, such as chemical test kits, and off-line devices, such as laboratory analysers.
The general requirements include functional facilities that MDs need to meet users’ applications and information that need to be included in associated documents.
The test procedures specify uniform methods to be used when determining key performance characteristics of MDs. The performance tests comprise testing carried out under laboratory and field conditions.
Statistical procedures are defined for evaluation of the test data. It is recognized that for some devices certain test procedures are not applicable.
Example values for performance characteristics for a selection of MDs for monitoring waste water effluents and receiving waters are detailed in Annex A for guidance.
This European Standard requires the manufacturer of a MD to provide more technical data for verification than does EN ISO 15839:2006 [5]. Consequently, EN ISO 15839 will be of greater assistance to manufacturers wishing to characterize a new device whereas this European Standard is more focussed on user requirements for the verification of manufacturer’s claims.

Specific sample integrity requirements are defined for samplers to be used for the collection of samples of final effluent or influent for the purpose of monitoring the performance of waste water treatment works, as required under the Urban Waste Water Treatment Directive (UWWTD). Samplers to be used for other industrial applications do not have to be assessed against these specific sample integrity requirements.
This European Standard does not cover the installation and on-going use of samplers.
